hesive Insect-Traps, of which the following is a specification. p y

One method of manufacturing adhesive insect-traps, commonly called fly-papers, consists in passing a strip of paper over a cylinder or drum coated with adhesive, the

drum having a transverse channel or channels, so that gaps are produced in the coating of adhesive applied to the strip. The strip is then commonly cut into sheets by hand, and tabs or eyes are attached to the sheets, at the edges free from adhesive, whereupon the sheets are rolled up singly, in order to be placed .in packing tubes.

These latter operations, performed by hand,

require a considerable number of operatives, and the object of the present invention is to provide a machine for performing them in a more expeditious and economical manner.

. The invention is illustrated in the accompanying drawings, in -which V Figure 1 is a plan view of a portion of the machine, Fig. 2 aside elevation, and Fig. 3 an end elevation, viewed from the left-hand side of Fig. 1. Fig. 4 is a plan view showing a portion of the machine not shown in Fig. 1. Fig. 5 is a section, showing part of the machine drawn to a larger scale.

In the drawings, 1 designates a table, on to which is fed the strip of paper 2, coated with adhesive inthe manner described. At the inner end of the table there is a vertical frame 3, on which slides a U-shaped member 4, supported by springs 4 and carrying a plate 5 mounted to rock on a horizontal shaft 10. This plate 5 normally lies parallel under a horizontal plate 6 fixed to the frame 3, and has on its upper surface a few short pins or spikes, whereby it is enabled to grip the front edge of a strip of paper 9 fed step by step between the plates 5 and 6. The paper strip 9. is fed between the plates by feed rollers 7 and 8 and carries adhesive eye-tabs 9 to be applied to the fly-paper.

, The portion of the strip 9 between the plates is cut 0s by a knife 13. The shaft 10 has cogs 11, which 'duringthe descent of the member 4 and plate 5 coact with cogs '12,

fixed to the frame 3, so that the plate 5 is rotated, so that the portion of paper cut off from the strip 9 and attached to the plate 5 comes to lie face downward, and is then pressed on to the fly-paper strip 2 on the table 1. The member 4 is moved downward by means of the main actuating shaft 14, to which are fixed two mutilated toothed wheels 15 meshing with racks 15 formed on the member 4. The tabs consisting of small sheets of paper out from the strip 9 are ap- For attaching the eyes, glue is applied to the strip 2 by a brush 16, before the member 4 has plied to those portions of the strip 2 which 7 are not coated with adhesive when the strip -2 is introduced into the machine.

completed its descent The brush 16 dips 1 into a heated glue-container 17, and has a" curved shank 18 resting, near the brush, on

"a roller 19. The shankhas an inclined part,

near the roller 19," joined to a horizontal part. A cam 20 on the shaft 14 actuates a double armed lever 21 1 engaged :with the shank 18, which parts are so arranged so that at properly timed intervalsthe shank, with the brush, is reciprocated, causing the brush 16 to sweep across the strip 2, at the place wherethe tabis to be applied. The inclined part of the shank, riding up and down the roller 19, causes the brush to rise out of. the glue container before it sweeps across the strip, and to drop back into the container after applying glue to the strip.

The knife 13 is actuated by a cam or finger 22 on the shaft 14. Before the gear wheels 15 engage with the racks 15*,for producing descent of the member 4, this finger. 22 acts on an arm 23 fixedto the knife, and depresses the latter to effect the cut, the knife being.then raised againby means of a 24, and temporarily retain the member 4 in i pivoted to a double armed lever 43.

its lowered position. Each of the horns 24 has an aperture, through which extends a .lug 27 formed on the upper end of a rod 28.

The rollers 26 then act on the lugs 27, and

impart further downward movement to the knife 30, which shears past the edge of the table 1, and cuts a sheet from the fly-paper strip 2. l/Vhen the rollers 26 clear the lugs 27 and horns 24, the knife 30 is lifted by a spring 31, and the member 4 is also lifted by the springs 4 The strip of paper 2 on the table 1 is held fast by a lever 34, which has a flat arm 34 extending partly across the table and lying on the strip; this arm is lifted at intervals by a cam 33 acting on the lever.

' The sheet of paper out from the strip 2 lies on one of a series of trays 32 mounted on endless conveyer chains 36 carried by sprocket wheels 39 fixed to shafts 37, 38.

Rotation of these shafts moves the trays transversely of the direction of feed. of the strip 2, and the trays are placed successively in alinement with the table 1. The shaft 37 is connected by a train of gear wheels 40 to a ratchet wheel 41 engaged by a pawl 42 To the latter is pivoted a rod 45, whereof the upper end lies in the path of a tappet on a wheel 44 driven by the shaft 14, so that depression of the rod 45 causes the ratchet wheel to rotate and impart through the gear wheels 40 and shaft 37 a lateral movement to the tray on which the sheet has been deposited. The movement imparted to the 7 tray somewhat exceeds the width of the 1, under the frame 3. One tongue of the gripper passes through a slot in the table 1, and comes to lie under the strip of paper. The other tongue has a tail, which travels along a curved guide 50, whereby the tongue is lifted, to lie over the strip, until the tail clears the guide, whereupon the lifted tongue drops on to the strip, so that the latter is drawn on to the tray 32 now in line with the table 1. The gripper is opened, to release the strip, when the tail referred to meets a curved guide 51 at the other end of strip on, two parallel guide wires 52, ap-

proximately at the level of the tray, and when the tray is shifted laterally, as described, after the cutting of the sheet from the strip, the sheet is guided by the said wires to two parallel rollers 53 having elastic bearings which allow them to move vertically. Between the rollers 53 lies a spindle 55 having a slot 54. The spindle 55 is axially movable and passes through a sleeve 57 rotatable in a frame part 56, and the rear end ofthe spindle is mounted in a bearing 58. To the sleeve is fixed a pinion 59 meshing with a large toothed wheel 61 fixed to a shaft 60 driven from the roller 47 by means of a train of gear wheels 62, 63, 64 so that the wheel 61 is driven by the main shaft 14 acting through the endless band 49.

The pinion 59 is integral with a clutch member 65, and a spring 67 coiled on the spindle tends to hold a clutch member 66 fixed to the spindle in engagement with the clutch member65, so that the spindle is rotated by the rotation of the pinion 59. The member 66 has a groove 68, within which is mounted a loose ring 69 having fixed to it a stud 70, and the latter projects into a slot 71 in a double armed lever 72, so that by rocking this lever the spindle 55 can be moved axially to disengage the clutch member 66 from the clutch member 65. The lever 72 is engaged with a bell-crank 74 pivoted at 73, and onearm of this bell-crank is bent, at 75, to form an inclined plane lying in the path of a roller 76 carried by the wheel 61, so that in the course of each revolution of the wheel the bell-crank is rocked, rocks the lever 72, and thus temporarily disengages the clutch. The clutch is thrown into engagement again by the action of the spring 67, which pushes the spindle forward, and the forward movement of the spindle is timed so that the slot 54 engages the sheet which has been brought up to the. rollers 53. The spindle is then rotated, and the sheet is rolled thereon, under suitable pressure exerted by the elastically mounted rollers 53. When the spindle is drawn back by the lever 72, the roll of paper is stripped off it by the sleeve 57, and drops into a box or basket which is placed in position to receive it.
